rt2ri {TargetSearch} | R Documentation |
Convert retention times to retention indices based on observed FAME RI and their standard values.
rt2ri(rtTime, observed, standard)
rtTime |
The extracted RT's to convert |
observed |
The observed FAME RT's |
standard |
The standard RI for each FAME |
Linear interpolation, interpolation outside bounds are done with continued linear interpolation from the last two FAME's
The converted RI
